He points his body towards you
Body language decoder:If he's across the room, take a peek at his hands and feet: We tend to point toward the object of our desire subsciously. When we find someone attractive, we'll often point (with our hands, feet or toes) toward that person.
If you're engaging in a conversation with him sitting next to you, it's even easier to tell: If he leans slightly forward and keeps his shoulders and upper body squarely facing you, it shows that he's deeply interested in you and what you have to say.
He gazes at your lips while you're talking
Body language decoder:Our eyes have a body language all their own. A major telltale sign of how we feel about someone is our gazing pattern: When we look at acquaintances, like at business meetings, we keep our gazes at eye-level, focusing on the other person's eyes and the bridge of the nose.
With friends or someone we like, we hold our eye contact longer than usual and our gaze moves down to include the nose and mouth. And if he's romantically drawn to you, the look can further drop down to include parts of your body like the neck or shoulders. This type of intimate gaze conveys interest. It's as if he can't resist caressing the rest of your face and hair with his eyes, or he's imagining what it feels like to kiss you on the lips.
